Unlike mass-produced Pet ID Tags, these pet tags are individually handmade at the time you place your order. The information is easily visible. Your ID info will not fade or scratch off. And due to "chewing mouths", we make sure every product we use is non-toxic and will not harm your pet. Only the best and safest materials are used for your fur-baby's tag. ID Information is directly engraved onto tag. A complimentary split ring is included with your tag so you can hang it from your pet's collar as soon as you receive it. Image goes on inside of bottle cap & is sealed with resin. The backside of bottle cap can be engraved w/ 3 lines of ID info. Size: 1 1/4" diameter
